  In the binding tool described in Patent Literature 1, when the belt-like piece is pulled up to release the engagement between the concave portion and the convex portion, the frictional force is concentrated on the convex portion, and the holding member and the base connected to the convex portion. A force in a direction away from the cover is likely to act on the material. Each time a new object is added or the object is taken out, the recesses and protrusions are disengaged, and the force away from the cover acts repeatedly on the substrate, causing the substrate to peel off from the cover. It becomes easy.

  In the binding tool described in Patent Document 2, three hinges are arranged in parallel in the longitudinal direction of the base material with a gap between the long sides of the base material. One hinge is provided at the central part of the long side of the base material, and two hinges shorter than the hinge provided at the central part are provided at both ends of the long side of the base material. The base end portion of the belt-like side is located next to the space between the hinge provided at the central portion of the long side and the hinge provided at the end portion of the long side, that is, next to the through hole. A reinforcing portion is provided on the long side of the base material inside the through hole. Although the reinforcing part is arranged, a through hole is provided next to the base end part of the strip, and since the hinge at the end of the long side is short, both end parts of the holding member are easily bent. . Therefore, when releasing the engagement between the concave portion and the convex portion, both end portions of the holding member bend, and both the concave portion and the convex portion move in the same direction (direction away from the cover), and the engagement between the concave portion and the convex portion is engaged. It is difficult to cancel.

  In the binding tool described in Patent Document 3, two hinge portions are arranged in parallel at the central portion of the base material along the longitudinal direction of the base material. The two hinge portions are both disposed between the two strips. That is, the hinge part which connects a base material and a holding member is short, and the both ends of the holding member are free ends. Therefore, when the engagement between the concave portion and the convex portion is released, both end portions of the holding member are easily pulled up and bent, and both the concave portion and the convex portion move in the same direction (direction away from the cover). It is difficult to disengage the protrusions.

  The present invention has been made in view of such circumstances, and when the engagement between the belt-like piece and the holding plate that holds the object to be released is released, the engagement between the belt-like piece and the holding plate is easily released. An object of the present invention is to provide a binding tool that makes it difficult for a material to be peeled off from a cover.

  The binding tool according to the present invention has a plate shape extending in one direction, and protrudes in the longitudinal direction of the base material from the base material fixed to the cover and each of the two short sides of the base material.
